Plastic behavior in ABAQUS: Metals and General Materials

Different material behaviors The material library in Abaqus provides a wide range of options for modeling various engineering materials, such as metals, plastics, rubbers, foams, composites, granular soils, rocks, plain and reinforced concrete, and also different material behavior models including elastic and plastic behavior. Material behaviors fall into the following general categories: Plastic and Elastic […]

Hyperelastic materials in ABAQUS

Hyperelastic materials are materials that can undergo large deformations without permanent damage. They are often used to model rubber-like materials, biological tissues, soft robots, and other applications that involve large strains. Hyperelastic materials can be characterized by a strain energy function, which relates the strain to the stored energy in the material. ABAQUS is a […]

UMAT and VUMAT: Advantages & Limitations

Overview of UMAT and VUMAT Subroutines The UMAT (User Material) and VUMAT (Vectorized User Material) subroutines are widely used in ABAQUS, a popular software suite for finite element analysis. These subroutines allow users to define custom material models and incorporate them into the simulation process. UMAT and VUMAT are user subroutines that allow users to […]
